SMALL-SIZED, MULTIPLE-SLOT ANTENNA Russian patent published in 1999 - IPC

FIELD: radar engineering; small-sized radar antennas for limited-displacement ships. SUBSTANCE: antenna is divided into functional and bearing parts made of different-density structural materials; additional bracing members are introduced to ensure permanent pressure of horn plates onto current-conducting sections of waveguide. In addition, new design of joints for waveguide flanges of antenna and transceiver are proposed to facilitate antenna installation and removal. EFFECT: reduced mass and improved mechanical strength of antenna; improved reliability of electric contact between radiating waveguide and horn plates. 2 cl, 4 dwg
